afferent signals. Motion of the body adds efferent signal information and leads to a more fluid perception of body transfer. When information from one form of signal (e.g. touch) does not match the signals from another sense (e.g. vision), the body still attempts to integrate this information. Specifically the rubber hand illusion is associated with activity in the multisensory areas, most notably the ventral premotor cortex. However, it remains to be demonstrated that this illusion does not simply reflect the dominant role of vision and that the premotor activity does not reflect a visual representation of an object near the hand. Drug-induced enhancement With ketamine, the body transfer illusion is ultimately enhanced and participants are more vulnerable to a false sense of limb ownership than without the use of ketamine. Although the precise nature of ketamine's impact is speculative, two features of its effects are noteworthy. First, it promotes an overall increase in the subjective and behavioral indices of the illusion. Second, this effect is found even when a sensory asynchrony is present, a manipulation that would normally reduce the experience of the illusion. This pattern may be understood in terms of the drug's impact on the top-down–bottom-up balance that would normally account for the illusion's characteristic features since ketamine produces an overall increase in tendency to the illusion, whereas this sensitivity to the coherence of visual and tactile input is preserved. A further possibility is that ketamine enhances the salience of the visual input (the sight of a rubber hand in a position compatible with one's own hand) at the expense of information arising from the temporal asynchrony between sensory inputs. This would explain why the presence of the rubber hand is enough to enable the illusion to persist, even when in attenuated form, when visuo-tactile inputs are asynchronous. A very similar effect occurs with the administration of the dopamine and noradrenaline releasing agent dextroamphetamine. The similarities include increased subjective reports of embodiment of the rubber hand during the illusion, and that the dextroamphetamine enhancing effect is also seen during sensory asynchrony. Mind-body connection Human bodily experience is characterized by the immediate and continuous experience that our body and its parts belong to us, often called self-attribution, body ownership and or mineness. It is unknown if the origin of body representation is innate or if it is constructed from sensory experience. A related, but distinct, bodily experience is self-localization
